纳米KMn_8O_(16)粉体的室温固相合成与表征

Using KMnO4 and MnCl2·4H2O as raw materials,nanometersized KMn8O16 was prepared by solid state reaction at room temperature.XRD,SEM,FT-IR and surface area measurement techniques were used to investigate the composition,size,morphology and properties of KMn8O16 powder.The results show that the powder has an average diameter of 20 nm with sphere-like and good dispersity and higher for H2O2 decomposition.
